Information from owned 78rpm. To the best of my knowledge, this
recording is the first one dealing with Early Music repertory
excluding Baroque era (Wanda Landowska is well known in the very
early part of the 20th century for her harpsichord music recordings).
I have seen a mention of a matrix number as stated above, but no
such number appears on my copy, maybe it is under the label!
